btrfs: sysfs: remove MIXED_BACKREF feature file 



This feature has been the default for about 13 year. At this point it's
safe to consider it an indispensable feature of BTRFS as such there's
no need to advertise it in sysfs. Remove the global sysfs feature file,
the per-filesystem feature file has never been there.
